Hi Jeffrey, thank you for reaching out.
It's not our policy to withhold refunds or rebates from our customers.
In the case of solar, you can request your credit balance to be refunded at any time, or to have it periodically refunded on a quarterly or annual basis, in the case of a government rebate that puts you into credit, you just need to get in touch with us to request the one time refund, or can leave it to accrue like the solar balance.
Cheers,
Xander
